if 1hp jet motar drop voltage when start from 220v to 120v give the reason and solution.
Answer / k.prakashchandra
It may be due to voltage drop in the line.Momentary drop
while starting only, can be ignored.Connect a load of about
500W and check for voltage drop.If the drop persists then
examine for loose connection/joint which could be any where
from dist transformer to the point of measurement .If you
don't detect any fault still, test the motor.Voltage between
neutral and the earth indicates a loose joint in the neutral.
